Gibraltar SBK-037-G Ball Knob 1 Inch Steel Threaded

Product Description

The GIBRALTAR SBK-037-G is a steel ball knob with a threaded hole mount, designed for use in mechanical assemblies, control panels, and equipment where a secure, hand-operable adjustment point is needed. The knob measures 1 inch in diameter with a smooth grip surface and a 5/16-18 threaded hole. The natural steel finish is left uncoated, making it suitable for applications where a clean metal look is preferred or where the knob will be installed inside an enclosure. Installers in HVAC, electrical, and general mechanical trades use this type of knob for fan controls, damper adjustments, and panel-mounted hardware.

This ball knob is suited for light to medium-duty mechanical applications in both residential and commercial settings. It threads onto 5/16-18 studs or threaded shafts and seats to a hole depth of 0.5 inches. Common uses include equipment control panels, HVAC service access points, and general hardware mounting where a compact, hand-tightened knob is required. The 1-inch diameter provides adequate grip area for finger-tightened adjustments without tools.

Compatibility

Installation Notes

Installation is performed by threading the knob onto a compatible 5/16-18 stud or shaft by hand. Power down or de-energize any equipment before servicing control panels or replacing hardware knobs. Verify thread engagement depth does not exceed 0.5 inches to avoid bottoming out before the knob seats fully. No special tools are required for standard installation.
